Question

does photosynthesis take place twenty - four hours of the day? why?​

Answer 1

Answer:

There are some plants that do perform photosynthetic metabolism 24hrs a day. They are CAM plants (Crassulacean Acid Metabolism). Some plant s like Kalachoe are obligate CAM, others are facultative CAM and only resort to it if water is short.

In a sense photosynthesis even in ordinary plants is a 24h job because most plants spend the night-time repairing and making new photosynthetic apparatus because during the day the chloroplasts are photodamaged

Answer 2

Answer:

Photosynthesis in green plants occurs only during the day.
